This invention relates to counting devices,

necting means which will operate a counter only upon the unlocking ofthe weighing mechanism and the loading of the platform.

Another object of the invention is to provide a device of this kind which'will operate without adding anything to the friction of a weighing mechanism.

Another object is the provision of connecting means of this character which is simple and compact in construction which is capable of installation by mere substitution for a connecting link of the weighing mechanism, and which is readily accessible for removal or adjustment. a 1

Other objects and advantages will be apparent from the following description, in which reference is had to the accompanying drawings illustrating a preferred embodiment .of my invention and wherein similar reference numerals designate similar parts throughout the several views.

In the drawings Figure I is a front elevational view of a coin-controlled weighing scale embodying my invention;

Figure II is a front elevational view on an enlarged scale, parts being broken away 0 and parts shown in section, of the portion of the weighing scale in which the counter is incorporated;

' Figure III is a further enlarged side elevational View of the counter and connecting mechanism; and

.Figure IV is asectional elevational view thereof taken from the opposite'side.

Referring to the drawings in detail, the

mechanism as shown is contained 'in'the upper end of a column 10f a coin-operated person weighing scale, the coin-controlled locking device being supported by a frame 2"interposed between the upper end of the column'l' and the lower end of 'the casing 3 which supports the l'oad-counterbalancing i and indicating mechanism-of thescale. A

7,. the lower end of which is threaded to receivea threadedplug 8. Extending verticallythrough the plug 8 and slidable there-f in is a rod 9, the lower end of which is rodl l {depends from the automaticload 7 connected by means of ahook toan( )ther platform lever mechanism of the scale. s

V "Mounted upon the rod 9 and slidable in I of the rod 9 is an ear 13 having an opening rod-10' which extends downwardly 'to fthe through which passes a pinlt secured to a lever--15 of the coin-controlledmechanism.

Thelever 15;:is locked against movement by means of teeth 16 which are withdrawn from coin slot 17. Since the present invention does not consist of the-coin mechanism .per

se, I shall not here describeit in detail, ;.It

will vbe seenthat the rod 9, ca Only bepulled downwardly when the lever 15 is released. v

If the scale be loaded without releasing the v lever 15' the, rod '9will be held againstidownward 'movementby the pin 14:. If howeve r,

the platform be'loaded' 'and the 1ev er'15 relit leased, the rod 9 will be pulled downwardly and a downward pressure will be exerted upon the casting 6 through the spring 12. This downward pressure on the casting 6 will in turn create a downward pull on the link 5 and rod 4 and the load-counterbalancing and indicating mechanism of the scale will thus be operated. The amount of pull on the rod 4 will be the same as though the connection between it and the rod 10 were a xtens ble in so t at t e. n rp sition olfeth e. spring, will; not aficci; the accuracyof'the scale.

Mounted upon the casting 6 is a counter L8: ofiithe Veeden type, and. connected torthe. operating arm 19 of the counter is, a lever] 2Q. which in turn is connected by means of a aga ns cre e t.
